Handheld power working machine

Abstract

A handheld power working machine includes a main body including a driving part, a working part provided in the main body and configured to drive by the driving part, and a gripper provided to be able to rotate with respect to the main body. The gripper includes a restriction part configured to be able to switch between at least a restriction state where the gripper is restricted from rotating with respect to the main body and a release state where the gripper can rotate by releasing the restriction state, and switching operation parts configured to perform switching operation to switch between the restriction state and the release state in the restriction part. Respective switching operation parts are disposed in at least one side and the other side of the gripper in a rotating direction.

The invention claimed is: 
     
       1. A handheld power working machine comprising:
 a main body including a driving part; 
 a working part configured to drive by the driving part; and 
 a gripper, 
 the gripper including:
 a restriction part configured to be able to switch between at least a restriction state where the gripper is restricted from rotating with respect to the main body and a release state where the gripper can rotate by releasing the restriction state; and 
 a plurality of switching operation parts, wherein: 
 
 the gripper is provided to be able to rotate, with respect to the main body, around a rotational axis extending from a front side, where the working part is located, to a rear side where the gripper is located, 
 the plurality of switching operation parts are each configured to perform a switching operation to switch between the restriction state and the release state in the restriction part, 
 the plurality of switching operation parts are disposed on at least a right side and a left side as viewed toward the front side of the gripper, 
 the switching operation parts include respective force point portions that are configured to be pressed while holding the gripper, 
 the switching operation parts are provided to be able to slide in a downward direction of the handheld power working machine with respect to the gripper, and 
 a direction in which the switching operation parts slide and a direction in which a force acts on the force point portions are parallel to one another. 
 
     
     
       2. The handheld power working machine according to  claim 1 , wherein:
 the switching operation parts are biased by a biasing member; and 
 the respective switching operation parts disposed on at least the right side and the left side of the gripper are substantially a same distance apart from the biasing member. 
 
     
     
       3. The handheld power working machine according to  claim 2 , wherein:
 the gripper is formed by a casing which is fabricated by combining a pair of case components having opening parts opposite to one another; 
 a plurality of parts are accommodated in the casing; and 
 one case component is combined into the other case component after the plurality of parts are accommodated in the one case component. 
 
     
     
       4. The handheld power working machine according to  claim 3 , wherein:
 the gripper includes a throttle lever to operate output of the driving part; and 
 the switching operation parts are disposed in positions in the gripper where the switching operation parts and also the throttle lever can be operated while the gripper is held. 
 
     
     
       5. The handheld power working machine according to  claim 2 , wherein:
 the gripper includes a throttle lever to operate output of the driving part; and 
 the switching operation parts are disposed in positions in the gripper where the switching operation parts and also the throttle lever can be operated while the gripper is held. 
 
     
     
       6. The handheld power working machine according to  claim 1 , wherein:
 the gripper is formed by a casing which is fabricated by combining a pair of case components having opening parts opposite to one another; 
 a plurality of parts are accommodated in the casing; and 
 one case component is combined into the other case component after the plurality of parts are accommodated in the one case component. 
 
     
     
       7. The handheld power working machine according to  claim 6 , wherein:
 the gripper includes a throttle lever to operate output of the driving part; and 
 the switching operation parts are disposed in positions in the gripper where the switching operation parts and also the throttle lever can be operated while the gripper is held. 
 
     
     
       8. The handheld power working machine according to  claim 1 , wherein:
 the gripper includes a throttle lever to operate output of the driving part; and 
 the switching operation parts are disposed in positions in the gripper where the switching operation parts and also the throttle lever can be operated while the gripper is held.
